Security and Energy Efficiency using WirelessHART Standard Sensor Networks

Security and energy efficiency in Wireless Sensor Network (WSN) is the most questing issue now-a-days because of various attacks on mobile nodes. Even though many algorithms have emerged to bring out security and energy efficiency, there are certain vulnerabilities like selfish nodes that try to save energy by not forwarding the packets and sleep deprivation attacks where an intruder overloads the target node with multiple requests which drains the energy of that node. Since a low energy node is more prone to security attacks, the throughput and hence the overall performance of the system will be lowered. WirelessHART is an emerging secure and reliable communication standard that aims in maximizing the utilization of wireless communication. This paper provides a summary of the energy efficiency and security measures provided by WirelessHART standard for effective wireless communication.
